922d314e8f Instruction scheduling itinerary for Intel Atom. 
Adds an instruction itinerary to all x86 instructions, giving each a default latency of 1, using the InstrItinClass IIC_DEFAULT.

Sets specific latencies for Atom for the instructions in files X86InstrCMovSetCC.td, X86InstrArithmetic.td, X86InstrControl.td, and X86InstrShiftRotate.td. The Atom latencies for the remainder of the x86 instructions will be set in subsequent patches.

Adds a test to verify that the scheduler is working.

Also changes the scheduling preference to "Hybrid" for i386 Atom, while leaving x86_64 as ILP.

Patch by Preston Gurd!

8fb06b3e8f Enable element promotion type legalization by deafault. 
Changed tests which assumed that vectors are legalized by widening them.

6f948be128 now that generic vector types aren't selected onto MMX registers, these 
tests don't need -disable-mmx.

52ceafa5c7 Use movaps / movd to extract vector element 0 even with sse4.1. It's still cheaper than pextrw especially if the value is in memory.
